I'm trying to get xawtv to work but I get the following error

bash-2.05b# xawtv
This is xawtv-3.86, running on Linux/i686 (2.6.9-gentoo-r6)
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

Error: Can't open display: :0.0
bash-2.05b#

I assume it's a permissions problem but it doesn't mean much to me. I'm
using the nvidia drivers on a geforce4 card and bt878 type tv card if it's
relevant. Any ideas?

It sound like you are trying to run xawtv from your root command using su
to become root. If you want to use xawtv as root user you should use sux
instead of su. You can install sux with the command: emerge -uvD sux

The you can just become root with X-access using the sux-command instead...

Do *NOT* run xawtv as root!!! Why are you doing that? If root is the
only user that can read from your TV card, then fix the TV card's
permissions.

Only people with the right .Xauthority file are allowed to connect to
your X server. Root hasn't got that file (or at least not a copy of
your .Xauthority), so that means no access. Fix your setup so you
won't have to run it as root anyway.

Sorry, my bad, I forgot to exit out of root!
I tried it under my user login but I get a segmentation fault,

bash-2.05b$ xawtv
This is xawtv-3.86, running on Linux/i686 (2.6.9-gentoo-r6)
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct
Segmentation fault
bash-2.05b$

Is this, as it suggests, actually a missing font problem? If so how do I
fix it?

Never, ever do that again, it's very dangerous

> I tried it under my user login but I get a segmentation fault,

Run it with 'gdb' and see where it segfaults. I must say I haven't got
xawtv running on my box either, I play TV with mplayer and I wrote a
separate application for zapping.

Well, it's apparently an incompatibility between xawtv and the nVidia
drivers. I solve it by running it as 'xawtv -noxv-video'.

Thanks for the help. If I use -noxv-video option it runs but only with
sound, the screen is black.
I've had it running with the nvidia drivers under Mandrake for ages, is
this a specific Gentoo problem?

Have you tried other output modes? Both grabdisplay and overlay work
for me, but perhaps you have problems with one or the other?

In a way, perhaps. Gentoo tends to use very new drivers, and those seem
to have a problem (and I think only in combination with a 2.6 kernel,
though I'm not sure. It was a while ago I solved this). BTW, does
'fbtv' from the framebuffer console work?

Sit back and watch the messages. This is actually more important than one
might think as there is a bug in GNU Mach whereby hitting a key during the
boot process causes the kernel to panic -- GNU Hurd Installation Guide

Thanks for the reply, I thought the grabdisplay option was for taking
screenshots! Grabdisplay displays perfectly but overlay still gives me a
blank screen.

Hmm, that's strange. Anyway, on my system overlay can't do full-screen
anyway, so I always use grabdisplay. Only problem is that high CPU load
will show as a choppy image. Did 'fbtv' work in the framebuffer
console? Some of it is similar to how overlay works with xawtv, but for
the console. Might help pin-point where the problem is. How about
mplayer with the 'xv' video output?
